Abstract: Abstract of the Disclosure A single-sample method for determining concentrations of individual lipoprotein classes and lipids in blood by turbidimetric measurement.  The blood serum is mixed with an ionic-strength-sensitive agent for forming an insoluble complex with the chylomicron, very low density, and low density lipoprotein classes, and the ionic strength of the mixture is raised in steps to cause progressive dissolution of each class of complex from that of highest density lipoprotein to that of lowest density lipoprotein.  Measurement of the turbidity due to the insoluble complex(es) present at each step allows calculation of the turbidity due to the complex of each individual lipoprotein class and from that the concentration of each lipoprotein class and lipid in the blood sample.

Abstract: ABSTRACT OF THE DISCLOSURE         A film tension absorbing mechanism is provided on a motion picture projector for absorbing film tension shock in the film strip.  The tension absorbing mechanism includes a first system comprising the combination of a pivotally mounted, biased film exit guide roller for absorbing a portion of the tension and a tension absorbing sprocket drive to permit relative movement between the film strip and the sprocket. The tension absorbing sprocket includes a sprocket wheel and a relatively movable sprocket tooth ring rotatably mounted for generally conjoint rotation.  The sprocket tooth ring is biased in a direction opposite the rotation of the sprocket wheel so that film tension shock can be absorbed as the sprocket tooth ring rotates relative to the sprocket wheel in a direction against the biasing force.  A second system also is provided and includes a bi-directional tension absorbing drive sprocket for absorbing film tension shock in two directions.  A sprocket tooth ring is mounted on a sprocket wheel for relative rotation therewith in two directions.  A biasing mechanism provides for a different biasing torque to be applied to the tooth ring as it rotates in one direction versus rotation in another direction rela-tive to the sprocket wheel.

Abstract: ABSTRACT OF THE DISCLOSURE      A valve assembly which mixes two components for delivery to a spraying apparatus.  The assembly is comprised of a core valve mounted in a housing or body which is secured in a chamber in a manner which provides passageways between the housing and the chamber.  A fluid is delivered to the core valve by a first conduit attached to the housing, while air is delivered to the chamber by a second conduit coaxial with the first attached to the chamber.  The core valve is operated by a plunger or push rod which opens the valve permitting the fluid to enter the chamber and causing it to be mixed internally with the air for delivery to a spraying nozzle device.  The valve assembly is operated simultaneously with the valves of the spraying device and may be incorporated into the spraying nozzle device or provided as an attachment thereto.  The valve is also incorporated into a spraying apparatus with an internal fluid mixing chamber which simultaneously mixes two fluids, then delivery mixture to a nozzle for blending with another fluid component.  The spraying apparatus is comprised of a gun body with an integral fluid mixing chamber, a nozzle body attached to the gun body, and a nozzle configured to blend two fluid components coming from the nozzle into a uniform spray.  The nozzle body is connected to the gun body by a hollow tubular nut, having a threaded nipple as a conduit for delivery of a fluid.  The nozzle body has a passageway in communication with the hollow nut for delivering the fluid to a chamber and valve connected to a central aperture of a nozzle removably attached to the nozzle body.

Abstract: Abstract The specification describes a fuel injection pump in which a distributor assembly is used with a pump unit for the distribution of equal fuel quantities to the cylinders of a multi-cylinder internal combustion engine.  The pump unit operates such that the number of deliveries of fuel metered by the pump equals the number of firing strokes in the engine with the distributor assembly connecting each of the cylinders within the engine in turn to the pump unit by means of delivery channels.  Only one cylinder is in communi-cation via the distributor with the pump unit at any one time.
